engine vin codes



I need some help with some vin numbers on the front of a 350 chevrolet motor. A friend of mine says it is a Corvette motor but doesn't no what year. It is a roller motor has a 638 block casting and the front number is V1025ZZZ any body have any idea?
Welcome to the CAC Jackson,
Unfortunately I can't give ya any info on engine block #'s......just thought I'd welcome you aboard. Hopefully someone will chime in with some answers for you

Have no idea what the ZZZ suffix is, never seen it and cannot find any reference.

The engine was assembled on October 25th. For the year you will need to check the casting date on the right rear by the bell housing flange (opposite of the casting number on the left rear side).

Please review the personal mail I sent you about the signature size.

Thank you
